Abstract

the mathematical model of thermal stress field and temperature field are built for the main member lay with different dropping velocity of temperature.the analytic solutions for the temperature and thermal stress are obtained by the integration transformation.the numerical results are shown in Figs.The effects of the cooling velocity on the temperature and thermal stress are investigated.The faster the cooling velocity ,the greater temperature grades,and the bigger tensile thermal stress within the surface of the main member lay.this bring the dangerous influence on the brittle property of material in low temperature.
